This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X600SH, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X600SH
The AirTAC Airtac SI100 Standard Cylinder SI100X600SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X600SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X600SH
The AirTAC SI100X600SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore, 600mm stroke, G1/2 port, and Viton H high-temperature seals (0-150 C). Delivering 3927 N push force at 0.5 MPa, it is replaced by the direct replacement SAI100X600SH. This current-production model shares the exact ISO 15552 mounting interface, bore, stroke, force, and port size, fitting existing fixtures perfectly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL and BSAI lock variants absent in the SI line.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X600SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X600SH Is Used
Large Part Ejection
Pushes heavy molded parts out of large presses using 5497 N of force at 0.7 MPa, with the 600mm stroke clearing wide tooling.
High-Temperature Handling
Transfers components in heated zones up to 150 C using the Viton H seal option, maintaining reliable actuation in thermal processes.
Replacing the Airtac SI100 Standard Cylinder SI100X600SH with the SAI100X600SH
To replace the SI100X600SH, order the SAI100X600SH, confirming the ISO 15552 mounting interface, 100mm bore, 600mm stroke, G1/2 port (PT/G/NPT thread), Viton H seal, and -S magnet for current AirTAC switches. For sizing down, an 80mm bore yields 2513 N push at 0.5 MPa; sizing up to 125mm provides 6136 N. Note that a plain cylinder drifts on air loss as the cushion only decelerates—for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 600mm stroke, prevent rod bending by using an external guide to counter side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X600SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X600SH FAQ
Yes, the SI100X600SH is discontinued. The direct replacement is the SAI100X600SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 600mm stroke, output force, G1/2 port, and mounting interface to fit existing fixtures.
The bore is 100mm with a G1/2 air port. Force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. It operates at 30-800 mm/s.
